CLEANER FOR BRUSHES OF PNEUMATIC MOUTHPIECES.

Specification of Letters Patent.

Patented Dec.. 22, i914.

Application led December 11, 1911. Serial No. 665,097.

erence being had to the accompanying drawings, forming part thereof.

This invention has reference to an improvement in devices whereby thebrushes of pneumatic mouthpieces may be cleaned.

The object of the invention is to so construct a cleaning device forbrushes of pneumatic mouthpieces that the cleaning brush may be receivedinto the said mouthpiece and engage the fluff and lint previously takenup by the brush.

Another object of the invention is to provide means whereby thepneumatic mouthpiece and its brush may be adjustably supported relativeto the cleaner device and that said brush may be rotatable.

rl`he invention consists in such peculiar features of construction andcombination of parts as shall hereinafter be more fully described andpointed out in the claims.

Figure 1, represents a side elevation of the carriage of a pneumaticcleaner showing the mouthpiece mounted in position to have its brushcleaned. Fig. 2, represents an enlarged sectional view of the mouthpieceand its brush mounted on the supporting members of the -cleaning device,the brush being shown in full. Fig. 3, represents an enlarged sectionalview taken on line 3 3 Fig. 1.

Similar numerals of reference designate corresponding parts throughout.

rlhe pneumatic mouthpiece herein referred to comprises a hood adapted tobe connected with the pipe of a suction svstem and containing arotatable brush. The hood or mouthpiece is adapted to be applied overthe doffer of a carding engine whereby the pneumatic suction draws thedust therefrom during the stripping operation, which latter isaccomplished by the brush contained within said mouthpiece or hood.after each of said stripping operations it is generally necessary toclean the stripping brush of the mouthpiece of the fiuii" or lintaccumulated thereon.

As shown in the drawings 5 represents the carriage of a pneumaticsuction machine having the suction pipe 6. On the carriage 5 is mountedthe base 7 having the upturned ends '8, 8 having slots to receive thebolts' 9, 9 whereby plates 10, having bearings at their upper ends, areadjustably secured to said ends 8, 8. VOn said carriage 5 are alsomounted the brackets 11, 11 on which is l mounted the cleaning strip 12furnished with 'the teeth or bristles Y13 usually in the nature of apiece of card clothing.

The mouthpiece, for which this cleaner is particularly adapted,comprises the hood 14 having the contracted opening or inlet 15 and theoutlet pipe 16 adapted to receive the end of the suction pipe 6. In theends of the hood 14 is journaled the shaft 17 having within said hood,the brush 18 and, at its outer end portion, the enlargements 19, 19 and20, 20, and the pulleys 21, 21 or similar devices whereby the shaft 17may be rotated.

The plates 10, 10 are adjusted and secured in place to rotatably supportthe shaft 17 at such a distance above the strip 12 that the cleanerformed by the bristles or wires 13 may enter the opening or inlet 15 andengage the fluff or lint on the brush 18.

After the stripping of one carding engine has been effected the hood111, with its shaft 17 and brush 18 is removed from the carding engineand is placed in position, as shown in Figs. 1 and 2, on the carriage 5and said carriage is moved to position for operating on another cardingengine. It is of course desirable and usually necessary that the findand lint stripped by the brush 18 from the first carding engine beremoved from said brush 18 before said brush is applied to the secondcarding engine and this is accomplished with the casing 14 and its shaft17 and brush 18 in the position shown in Figs. 1 and 2 by operatortaking hold of the pulleys 21, 21 and rotating the shaft 17 and itsbrush 18 whereby the fluff and lint carried by the brush 18 is strippedaway or taken up by the teeth or bristles 18. During such rotation ofthe shaft 17 its longitudinal movement is prevented by the enlargements19, 20 between wliich the plates 10, 10 engage the shaft 17.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A cleaner for carding brushes comprisi' ing a basemember provided with upturned Slotted ends, bearings adjustably securedto said slotted ends,-a-cleaningstrip rigidly qstrip, Aa shaftfhaving a`brush thereon journaled n saidY bearings, and means upon said shaftwhereby longitudinal movement of `the same is restricted to operativelyposition the brush relative to the cleaning strip.

3. A cleaner for carding brushes compris- -ing -a -pair of verticallyadjustable open ended bearings, acleaning strip supported between saidbearings, a brush shalt provided vWith spaced enlargements adjacent 20each of its ends, said bearing members supyportmgsaid shaft and engagmgsaid enlargements whereby the shaft may be adjusted vertically andsupported against longitudinal movement.
